Abstract

We report a polarizationbeam splitter (PBS) utilizing the anomalous reflection and transmission of an anisotropicmetamaterial slab. By properly design of the constitutive tensors of the slab, PBS is achieved with little dependence on incident angle and slab thickness. The realization of the proposed PBS in the optical range is achieved by layered metal-dielectric nanostructured system, which could be modeled as an effective anisotropicmetamaterial with the desired constitutive tensors. The full-wave electromagnetic simulation has confirmed the optical polarization splitting with an extinction ratio of over by a slab of an alternating silver and silicon carbide multilayer.
